This study investigates the scaled-up carbonation of process liquor generated from pitchblende and uraninite ore processing, focusing on using flue gas as a carbon dioxide source. Initially, laboratory-scale carbonation trials were conducted in a 5-liter batch reactor using pure carbon dioxide, establishing baseline parameters. Subsequently, pilot-scale experiments employed flue gas from light diesel oil (LDO) fired boilers in the same 5-liter reactor. Reaction kinetics were analyzed, and chemical equations were modeled using “Python” computer language. Following successful pilot-scale results, industrial-scale experiments were performed in a 200-liter batch reactor, with kinetic studies and equation modeling implemented using Python. This paper presents a comprehensive comparative analysis of the carbonation process across laboratory, pilot, and industrial scales, highlighting the impact of scale-up on reaction kinetics and efficiency. The comparative study is validated through Python-based analysis, demonstrating the feasibility and effectiveness of utilizing flue gas for large-scale carbonation of mining and mineral ore processing liquors.
